ENABLE
Output enable input terminal
All outputs ( OUT0 to OUT7 ) are disabled when the ENABLE terminal is driven High, and
enabled when it is driven Low.
SERIAL-OUT Serial data output terminal. Serial data is clocked out on the falling edge of CLOCK.
R-EXT
An external resistor is connected between this terminal and ground. OUT0 to OUT7 are adjusted
to the same current value.
